 Agoutis have been born, and a clutch of Chinese Goose-eggs have been 

 hatched in the Gardens. The new Seal pond, in which Penguins and 

 Seals may now be seen disporting themselves, is a great addition to the

DUBLIN MICROSCOPICAL CLUB. 



April 8. — The Club met at Leinster House, Prof. G. H. Carpenter, 

 President, in the Chair. He showed specimens of a new genus and 

 species of CoUembola, brought from South Victoria Land by the National 

 Antarctic (" Discovery ") Expedition. The insect will be shortly described 

 and figured in the volumes of " Results " in course of publication by the 

 British Museum. 



J. N. Hai^berT exhibited a Stone-fly Capnia atra, Morton (previously 

 unrecorded from Ireland), both sexes of which were found under stones 

 on the shore of the Devil's Punch-bowl, on Mangerton Mountain, in 

 June, 1905. The male of this species first came under Mr.Morton's notice 

 from Finnish Lapland, when he pointed out its specific distinctness 

 from the commoner Capnia nigra, Pictet {Trans. Entotn. Soc. London, 1896). 

 The species has vsince been found in various localities in Northern 

 Britain. 



Dr. R. F. ScHARFF exhibited a specimen of the Woodlouse Arnia- 

 dillidinm piciiim, taken by Mr. H. N. Foster in a greenhouse at Holywood, 

 Co. Down. He demonstrated the salient features of distinction in the 

 antennae and tail-appendages between it and Arniadillidiiim pnlchellum, 

 which was already known as an Irish species. He also showed specimens 

 of the latter collected by Mr. J. N. Halbert at Carrickmines in Co. 

 Dublin, being the first record for the east of Ireland. 



R. Southern, B.Sc, showed specimens of the Nematode worm, 

 Tylcncholainiits ntinimns, De Man, belonging to the family Auguillulidae 

 These worms, in company with two other species, were found under the 

 epidermis of roots of Sweet Pea from Donnybrook. Some of the plants 

 were diseased, whilst others, which also harboured these worms, were 

 apparently uninjured; so that the question as to the disease being 

 caused by these nematodes is still unanswered. They were hardl}- present 

 in sufficient numbers to have a directly injurious effect. Possibly the
